Biography

Michael Ruppert received the Dipl.-Ing. Degree in automation technology in production, with a specialization in systems theory and automatic control, from the University of Stuttgart, Germany, in 2013. In 2017, he received the Ph.D. degree with Excellence Award in electrical engineering from The University of Newcastle, Australia where he is now a Postdoctoral Research Fellow with the School of Electrical Engineering and Computing.

Dr Ruppert’s research topics are situated within the area of Micro Precision Mechatronics and as such bridge the gap between classical electrical / control engineering and emerging applications in the field of microelectromechanical systems, high performance microscopy and nanotechnology. His recent work has focused on the development of estimation, control and self-sensing approaches for microelectromechanical (MEMS) systems such as piezoelectric microcantilevers and nanopositioning systems for multifrequency and single-chip atomic force microscopy.

New Paradigm in Microscopy: Atomic Force Microscope on a Chip

As a Visiting Researcher, he was with the Mechanical Engineering Department, University of Texas at Dallas, USA. During his research visit he worked on the fabrication of piezoelectric microcantilevers in the clean room and lead-authored the publication on the first silicon-on-insulator MEMS on-chip atomic force microscope, recently published and identified as a JMEMS RightNow paper in the IEEE Journal of Microelectromechanical Systems, and which was highlighted in the IEEE Spectrum magazine. During his visit, Dr. Ruppert also consulted to Zyvex LABS, Richardson, USA on the analysis of process stability of scanning tunneling microscope enabled nanolithography.

Dr Ruppert received the Academic Merit Scholarship from the University of Stuttgart, the Baden-Württemberg Scholarship, and held Postgraduate Research Scholarships with the University of Newcastle and with the CSIRO, Clayton, VIC, Australia. Dr Ruppert’s research has been recognized with Best Conference Paper Finalist Awards at the 2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS) and a the 2013 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM). In 2018, the article Multimode Q Control in Tapping-Mode AFM: Enabling Imaging on Higher Flexural Eigenmodes published in IEEE Transactions on Control Systems Technology received the 2018 IEEE TCST Outstanding Paper Award.
